CVE-2022-50642
In the Linux kernel, the following vulnerability has been resolved:
platform/chrome: cros_ec_typec: zero out stale pointers
cros_typec_get_switch_handles allocates four pointers when obtaining
type-c switch handles. These pointers are all freed if failing to obtain
any of them; therefore, pointers in port become stale. The stale
pointers eventually cause use-after-free or double free in later code
paths. Zeroing out all pointer fields after freeing to eliminate these
stale pointers.
